[0007] Preferably, the pattern is centered on the center straight groove, and the left and right patterns are inversely symmetrical, and the inner and outer patterns are identical in shape.

[0008] Preferably, the shoulder pattern is formed into two block patterns shifted and overlapped by thin oblique straight grooves.

[0009] Preferably, the short groove is arranged at an angle of 22 degrees.

[0010] Preferably, the steel sheet bar is provided in a sawtooth-shaped 3D structure.

[0011] Preferably, the pattern on the surface of the carcass is more than 70%.

[0012] The utility model has the beneficial effects that:

[0013] The utility model provides a brand -new tire pattern, and limit a kind of all -season commercial vehicle tire, through the development of innovative technology, double-guided pattern design, three straight groove guided pattern design, tread pattern shift design, center groove left and right pattern transverse groove communication design, center pattern groove groove both sides additional groove design, sawtooth snow 3D thin steel piece rib design, wear-resistant pattern design and so on Feature, meet all -season use, especially suitable for european market popularization.

[0019] The preferred embodiments of the utility model are described in detail below in combination with the drawings, so that the advantages and characteristics of the utility model can be more easily understood by those skilled in the art, so that the protection scope of the utility model can be more clearly and explicitly defined.

[0020] Embodiment:

[0021] As shown in Figure 1 and Figure 2 , a kind of all -season commercial vehicle tire, protect the innovative structure of the pattern on the surface of carcass, according to convention, the surface of carcass 1 is provided with pattern, it is double-guided pattern design, specifically, with center straight groove 5 as center, left and right pattern is reverse symmetry, inside and outside pattern shape is same, so that positive and negative installation can be used, facilitate commercial vehicle replacement and later change, prolong service life, improve economy.

[0022] As shown in Figure 1 and Figure 2As shown in the figure, the pattern structure is provided with three straight grooves, the straight grooves include a center straight groove 5 and side straight grooves 6 distributed on both sides, the pattern is divided into a center pattern 2 and a shoulder pattern 3 by the three straight grooves arranged in parallel in the circumferential direction, the center straight groove 5 is designed to be narrower than the side straight grooves 6 on both sides, the center straight groove has the functions of drainage and strong guidance, and the steering is labor-saving and easy; the side straight grooves 6 on the outside are widened to increase the drainage performance, and the steering performance on the snow is maximized.

[0023] As shown in the figure, Figure 1 and Figure 3 As shown in the figure, the pattern structure is provided with a shoulder pattern 3 which is spaced by a fine inclined straight groove 9 to form two block pattern shifts which are staggered, each pitch is clear in hierarchy, the noise of the tire can be reduced, the lateral snow performance is strengthened, the ground holding performance is stronger, and the rigidity of the shoulder pattern can be rebalanced by the design, and the wear resistance is strengthened.

[0024] As shown in the figure, Figure 1 and Figure 2 As shown in the figure, the pattern structure is provided with a center groove left and right pattern transverse groove communication, and the width direction of the center pattern 2 is provided with a transverse groove 4 which is communicated with the three straight grooves; the communication design is mainly to balance the rigidity of the center pattern of the tire, to improve the ground holding capacity of the commercial load, and to increase the drainage channel, that is, the longitudinal and transverse directions can be quickly drained, so that the tire tread is fully contacted with the ground, and the wet ground holding capacity is improved.

[0025] As shown in the figure, Figure 1 , Figure 2 and Figure 3 As shown in the figure, the pattern structure is provided with a center pattern groove groove side additional groove design, and on each pitch of the two sides of the center straight groove 5, a short groove 7 is embedded on the edge of the parallelogram pattern block, the short groove 7 is arranged in a 4mm long inclined direction at an angle of 22°, so that the ground holding capacity of the tire tread on the snow is fully improved. In order to meet the use in all seasons, especially in winter, it is necessary to ensure the ice and snow ground holding capacity of the tire tread and to soften the rigidity of the tire tread, so that a steel sheet bar 8 is inserted on all pattern blocks on the entire pattern surface, and the steel sheet bar is arranged in a zigzag 3D fine steel bar, a large number of zigzag 3D fine steel sheet bars are interlocked, and the braking capacity on dry and wet ground is improved.

[0026] As shown in the figure, Figure 1 and Figure 2 The entire tire tread is provided with block patterns, the block patterns increase the rigidity, support the use of commercial vehicle load demand, are more resistant to load, especially have stronger over-bending capacity, improve the safety of commercial vehicles, and the block patterns are beneficial to the passing performance of the commercial vehicle; in addition, the pattern on the surface of the tire body is more than 70%, so that the entire pattern has balanced rigidity, driving is more wear-resistant and economical, and is especially suitable for the market demand of commercial vehicles.

[0027] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, which are made by using the content of the present application specification and drawings, are also included in the patent protection scope of the present application.
